## Common Nonexceedance Probabilities

### Description

This function returns a vector nonexceedance probabilities.

### Usage

    nonexceeds()

### Value

A vector of selected nonexceedance probabilities useful in assessing the “frequency curve” in hydrologic applications (noninclusive). The nonexceedance probabilities extend further into the right-hand tail of the “distribution” to the 0.996 and 0.998 nonexceedance probability values as these are equivalent to the 250- and 500-year events respectively. The relation between annual recurrence interval and nonexceedance probability (when annual data are analyzed) is

F = 1 - frac{1}{T} mbox{,}

where T is the T-year event.
